Unlocking an iPhone involves removing the security measures that restrict access to the device and its data. This process can be necessary for various reasons, such as when you forget your passcode, purchase a used iPhone, or need to switch carriers.
Unlocking an iPhone offers several benefits. It allows you to use the device with any compatible carrier, giving you greater flexibility and choice in your mobile service provider. Additionally, unlocking can increase the resale value of your iPhone, as it makes it more appealing to a wider range of potential buyers.
